I am trying to make a 64-bit build of Boost 1.31.0 on IRIX using the MIPSpro Compilers 7.3.1.3m, but I cannot seem to get any of the dynamic libraries to link. The bjam command line I am using is this: bjam -sTOOLS=mipspro "-sBUILD=debug release <runtime-link>static/dynamic <address-model>64" (I have $PYTHON_ROOT pointing to a 64-bit build of Python 2.2.3.) All link actions for dynamic libraries fail thusly: ld64: FATAL 12 : Expecting n64 objects: /usr/lib32//c++init.o is n32. Looking at the output after the failed action, I see -L/usr/lib32 in the link line, and I am pretty sure it should not be there. The complete output of the first failed action is this: "/usr/bin/CC" \ -o "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/libboost_date_time-mp-d-1_31.so" \ "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/greg_month.o" "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/greg_weekday.o" "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/date_generators.o" \ \ "-DBOOST_DATE_TIME_POSIX_TIME_STD_CONFIG" "-DBOOST_ALL_DYN_LINK=1" \ "-nostdinc" "-LANG:std" "-OPT:Olimit=0" "-OPT:IEEE_NaN_inf=ON" "-no_auto_include" "-64" "-mips3" "-O0" "-g" "-INLINE:none" \ \ \ "-I/usr/include/CC" "-I//usr/include/CC" "-I/mnt/rigby/home13/users/patrick/src/Boost/blah/boost_1_31_0/boost/compatibility/cpp_c_headers" \ "-I/usr/include" "-I//usr/include" "-I/mnt/rigby/home13/users/patrick/src/Boost/blah/boost_1_31_0" \ "-nostdlib" "-shared" \ \ \ \ "-L/usr/lib32/mips3" "-L/usr/lib32/" "-L//usr/lib32/mips3" "-L//usr/lib32/" "-L/usr/lib32/mips3" "-L/usr/lib32/" "-L//usr/lib32/mips3" "-L//usr/lib32/" "-L/usr/lib64/mips3" "-L/usr/lib64/" "-L//usr/lib64/mips3" "-L//usr/lib64/" \ "-lm" All the object files being linked in this case are 64-bit, so I think that the compile action is behaving correctly. Am I forgetting something in my bjam command or otherwise misusing bjam? -Patrick -- Patrick L.
